DLL调用 ​

c
int32_t TcpClientDestroy(int64_t instance, int64_t client_handle);

参数说明 ​

参数名类型说明
instance长整数型OLAPlug对象的指针，由 CreateCOLAPlugInterFace 接口生成。
client_handle长整数型客户端句柄。

示例 ​

SDK 调用 ​

cpp
#include "OLAPlugServer.h"

OLAPlugServer ola;
long client = ola.TcpClientCreate(nullptr, 0, 1);
if (client != 0) {
    // enable_packet_protocol=1 启用分包协议
    ola.TcpClientConnect(client, "127.0.0.1", 9000);
    // 退出前销毁，会自动断开连接

返回值 ​

返回值说明
（返回值）整数型，1 成功，0 失败。

注意事项 ​

项目说明
销毁前会自动断开连接销毁前会自动断开连接。
销毁后销毁后，客户端句柄失效，不可再使用。
销毁会释放所有相关资源销毁会释放所有相关资源。
建议在程序退出前销毁所有客户端建议在程序退出前销毁所有客户端。
销毁后不会再触发回调销毁后不会再触发回调。
